Definitions

  • the present invention relates to a filter cassette for a vacuum cleaner appliance, wherein the filter cassette is positionable in the vacuum cleaner appliance such that the filter cassette is positionable in an airflow drawn in by the vacuum cleaner appliance, wherein the filter cassette contains substantially a lateral surface, an upper opening, and a lower opening, such that the drawn-in airflow, in order to filter out dirt particles, can flow into the filter cassette through the lower opening and out of the filter cassette through the upper opening.
  • Filter cassettes that can be received in a vacuum cleaner appliance, in particular in a vacuum cleaner, are very widely known from the prior art.
  • Such filter cassettes usually contain a rectangular frame, which holds a filter element.
  • the filter element serves to filter dirt particles out of an airflow that is drawn in by the vacuum cleaner appliance.
  • the filter cassettes that are known from the prior art are usually arranged between a collection container and a suction head of the vacuum cleaner appliance.
  • the collection container serves to collect dirt particles that are filtered out of the drawn-in airflow
  • a suction head serves to generate the drawn-in airflow, with which the dirt particles are picked up.
  • the suction head In order to arrange the filter cassette at the intended position in the vacuum cleaner appliance and between the collection container and the suction head, the suction head has to be separated from the collection tank beforehand. Subsequently, the filter cassette is positioned in a receiving device for the filter cassette.
  • the filter cassettes that are known from the prior art contain a sealing element that seals the filter cassette off from the receiving device in an airtight manner when the filter cassette is located in the receiving device.
  • the prior art makes the fitting of the filter cassette in the vacuum cleaner appliance and the replacement of the filter cassette complicated, time-consuming and difficult. Furthermore, the filter cassette and in particular the sealing element are not always reliably positioned correctly.
  • An object of the present invention is to provide a filter cassette for a vacuum cleaner appliance and a vacuum cleaner appliance having a filter cassette receptacle for receiving a filter cassette, with which the above-described problem can be solved and the arrangement of the filter cassette properly in the vacuum cleaner appliance can be made quicker and easier.
  • the present invention provides a filter cassette for a vacuum cleaner appliance, wherein the filter cassette is positionable in the vacuum cleaner appliance such that the filter cassette is positionable in an airflow drawn in by the vacuum cleaner appliance, wherein the filter cassette contains substantially a lateral surface, an upper opening, and a lower opening, such that the drawn-in airflow, in order to filter out dirt particles, can flow into the filter cassette through the lower opening and out of the filter cassette through the upper opening.
  • At least one first and second sealing element are provided, wherein the first sealing element extends in a first plane and the second sealing element extends in a second plane, and wherein the first and second planes are arranged at an acute angle to one another, such that the second sealing element is oriented substantially horizontally when the filter cassette is positioned in a filter cassette receptacle of the vacuum cleaner appliance, wherein the filter cassette receptacle is accessible from outside the vacuum cleaner appliance.
  • the acute angle between the first and the second plane may be possible for the acute angle between the first and the second plane to have a value of 45°. As a result, a virtually optimal contact pressure on the first and second sealing elements can be generated.
  • the substantially wedge-like arrangement of the first and second sealing elements and the arrangement of the filter cassette at a flat angle in the filter cassette receptacle helps the filter cassette to be clamped in place in the filter cassette receptacle of the vacuum cleaner appliance on account of the dead weight of the filter cassette and thus to be positioned optimally in a sealed-off manner.
  • the flat angle for the arrangement of the filter cassette in the filter cassette receptacle relates to a central axis of the filter cassette with respect to the horizontal.
  • the invention also provides a vacuum cleaner appliance having a filter cassette receptacle for receiving a filter cassette.
  • the filter cassette receptacle extends substantially in a center plane that is arranged at an acute angle, in particular 45°, to a parting plane.

  • the filter cassette 1 contains a first side wall 1 a , second side wall 1 b , third side wall 1 c , and fourth side wall 1 d .
  • the first, second, third and fourth side walls 1 a , 1 b , 1 c , 1 d together form a lateral surface 3 encircling the filter cassette 1 .
  • the lateral surface 3 contains an upper side edge 3 a and a lower side edge 3 b . Both the upper and lower side edge 3 a , 3 b encircle the lateral surface 3 .
  • the third and fourth side walls are not shown, only indicated.
  • the lateral surface 3 encloses a cavity 4 .
  • the cavity 4 serves to receive and hold a filter element 5 .
  • the filter element 5 serves to filter out and retain dirt particles that are located in an airflow LS (See, e.g. FIG. 4 ) flowing through the filter element 5 .
  • the airflow LS is generated by the vacuum cleaner appliance 2 , which will be described in detail below.
  • the filter cassette 1 contains a first sealing element 6 and a second sealing element 7 .

  • the second sealing element 7 extends along the second and fourth side walls 1 b , 1 d at an acute angle ⁇ to a horizontal line.
  • Acute angle ⁇ here is shown solely schematically but is 45 degrees in the exemplary embodiment as noted in FIG. 1 .
  • the second sealing element 7 is thus located in the vicinity of the upper side edge 3 a of the filter cassette 1 along the first side wall 1 a .
  • the second sealing element 7 is located in the vicinity of the lower side edge 3 b of the filter cassette along the third side wall 1 c .
  • the second sealing element 7 extends from top (from the vicinity of the upper side edge 3 a ) to bottom (into the vicinity of the lower side edge 3 b ).
  • the second sealing element extends from bottom (from the vicinity of the lower side edge 3 b ) to top (into the vicinity of the upper side edge 3 a ).
  • the first and second sealing elements 6 , 7 form respective wedge-like surfaces between one another.
  • first sealing element 6 extends in a first plane A and the second sealing element 7 extends in a second plane B.
